一些 ImageMagick 命令

谢益辉 / 2018-04-23

偶尔需要简单处理一下图片，无奈 ImageMagick 功能繁多，实在记不住命令行，每次都得搜一遍。索性开个帖子积累一下笔记：

  • 按特定百分比缩放图片：

    convert -resize 25% INPUT OUTPUT

  • 加黑框：

    convert INPUT -shave 1x1 -bordercolor black -border 1 OUTPUT

  • 白色转为透明色：

    convert INPUT -fuzz 20% -transparent white OUTPUT.png

  • 横向合并多幅图片：

    # 合并五幅图 0.png, 1.png, ..., 4.png
montage [0-5].png -tile 5x1 -geometry +0+0 out.png
